أَفَحَسِبَ ٱلَّذِينَ كَفَرُوٓا۟ أَن يَتَّخِذُوا۟ عِبَادِى مِن دُونِىٓ أَوْلِيَآءَ ۚ إِنَّآ أَعْتَدْنَا جَهَنَّمَ لِلْكَـٰفِرِينَ نُزُلًا Qur’an Al-Kahf (18:102)Afahasiba allatheena kafaroo an yattakhithoo AAibadee min doonee awliyaa inna aAAtadna jahannama lilkafireena nuzulan
This is an allusion not only to the worship of created beings or forces of nature, but also to the popular belief that saints, whether alive or dead, could eflfectively "intercede" with God in behalf of anyone whom He has rejected.
I.e., of God's oneness and uniqueness, and hence of the fact that no created being can have any "influence" on God's judgment.
i.e., Jesus, Ezra, and the angels.
